Copy T/ghc/includes/ghcautoconf.h, T/ghc/includes/DerivedConstants.h, and T/ghc/includes/GHCConstants.h to H/ghc/includes. Note that we are building on the host machine, using the target machine's configuration files. This is so that the intermediate C files generated here will be suitable for compiling on the target system.

Touch the generated configuration files, just to make sure they don't get replaced during the build:
